Description Malte S. Stretz 2013-04-08 09:58:17 UTC 
Application: krunner (0.1)
KDE Platform Version: 4.10.2
Qt Version: 4.8.2
Operating System: Linux 3.5.0-27-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I Use krunner a lot: Alt+F2, type quickly, hit return. Every now and then KRunner crashes. This time while I was typing kmail, I think after the second or third letter.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Run Command Interface (krunner), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

This time I tried to start Amarok. I think it crashed at ama.

The internal code structure has changed quite a bit. I'm going to mark this as FIXED. Please re-open if you experience this crash with Plasma 5.
